Installation
Cables
STEP 1.
Remove the cover panels by unscrewing the pins
connecting the panels to the front of the
enclosure. Lift the front of each panel upwards
and pull outwards to disengage the tab at the
back of the panel from the slot at the bottom of
the operating mechanism. See Figure 16.
STEP 2.
When pulling cables, the hinged roof can be
placed in a second, more vertical position. While
pushing up slightly on the hinged roof, release
the latches on the “hold-open” mechanisms on
both sides of the switchgear enclosure. Lift the
hinged roof to the second, more vertical position;
the “hold-open” latching mechanism will
automatically engage. See Figure 17 on page 19.
Lifting the hinged roof to the second, more
vertical position is a two-person exercise,
especially on switchgear assemblies having four
or more ways.
NOTICE
The hinged roof cannot be placed in
the second, more vertical position if the
hinged-roof counterweights are attached.
If necessary, remove the pins connect-
ing the upper and lower lever arms of the
counterweight mechanism. See Figure 18
on page 20.
DANGER
Before energizing the switchgear, replace
the shipping covers on all bushings and
bushing wells with elbows or insulated pro-
tective covers or caps.
Failure to replace
the shipping covers on all bushings with
elbows or insulated protective covers or
caps can result in a flashover and serious
personal injury or death.
STEP 3.
Remove the shipping covers from the 600-ampere
bushings (yellow) or 200-ampere bushing wells
(orange). See Figure 20 on page 21.
Figure 16. To remove cover panels, unscrew the pins connect-
ing the panel to the enclosure (a), lift up on the panel and pull
outward (b).
